SCM-20 Tower

The SCM20SL Tower is ATC’s flagship 2-way floor-standing loudspeaker and is the ideal choice in modestly sized rooms, but where performance cannot be compromised.  It is available in both passive and active bi-amplified versions, the SCM20PSLT and SCM20ASLT respectively.

Its sealed cabinet design ensures excellent timing, useful low frequency output below the cut-off and that the speakers can be placed relatively close to walls without excessive low frequency ‘boom’.

Both the mid-bass driver and tweeter are handmade by ATC.  The bass driver is a 150mm driver with huge 3”/75mm voice coil and massive, long-gap (short-coil) motor assembly featuring ATC’s proprietary ‘SL’ motor technology.  The tweeter is a 25mm soft-dome part featuring a dual-suspension and very high energy 2.1 tesla motor.  Together, they form the basis for an exceptional 2-way monitor loudspeaker capable of delivering outstanding resolution and musicality.

Driver integration withing the passive model is handled 2^nd order crossover featuring oversize air-core inductors which are would in-house by ATC.  Capacitors are all high voltage polypropylene film types and the input features heavy duty binding posts in a bi-wire configuration.

The active versions features an on-board ATC bi-amp pack featuring 2-way active crossovers and Class A/B MOSFET power amps, delivering a total power output of 250W.  The active crossovers superior accuracy and phase coherence, plus the removal of the lossy passive components between power amp and drive units deliver a level of performance that simply can’t be matched by competing passive designs.

The SCM20's cabinet is constructed to be heavy and inert, with bitumastic damping panels deployed at critical positions to minimise cabinet colouration.
